SHEARS.

Specification of Letters Patent.

Patented Sept. 27, 1921.

Application filed September 20, 1920. Serial No. 411,407.

T 0 all whom it may concern:

Be it known that I, OSCAR A. Gonrzn, a citizen of the United States, residing at Golden, in the county of Jefferson and State of Colorado, have invented certain new and useful Improvements in Shears, of which the following is a specification.

This invention relates to shears for cut ting comparatively soft metal, and more particularly to shears specially adapted for trimming and cutting the metallic slugs formed by casting in linotype machines; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of a shears constructed according to this invention. Fig. 2 is a plan view, and Fig. 3 is an end View, of the same.

A platen 5 is provided for the metallic slug to rest on, and is preferably supported on legs 6. A cutting blade 7 is secured to the rear edge of the platen, and is arranged level with the top of the platen. An up right 8 is secured to one end portion of the platen, and has a notch or space 9 at its rear side. A vertical bar 10 is secured to the upright by bolts 12, and forms a cover for the space or notch 9. A cutter lever 14 is provided, and one end portion of it is pivoted by a pin 15 to the upright 8 and bar 10 in the notch or space 9. A cutter blade 17 is secured to the front side of the lever 14. This cutter blade has a cutting edge which works against the cutting edge of the blade 7. This cutting edge is preferably straight.

A spring 18, for normally holding the cutter lever in a raised position, is secured between the said lever and the upright 8. A guide for the cutter lever is provided, and is formed by an arm 20 which projects from the vertical bar 10, and extends diagonally of the platen and above the level of its top side, so that the cutter lever and the arm 20 are substantially parallel to each other when the cutter lever is raised to the full extent necessary to permit a slug to be in that the blades will work close to each other without friction, and thereby cut the slug without forming any ragged edges. The guide arm is adjustably secured to the upright, packing pieces 21 being inserted be tween the bar 10 and the upright 8, or any other suitable means being provided for enabling the pressure of the guide arm against the back of the cutter lever to be varied.

What I claim is:

A shears for cutting soft metal, comprising a stationary platen, a stationary blade secured to the rear edge of the platen and having a sharp cutting edge, an upright secured to one end of the platen, a bar having its end portions secured against the rear side of the upright, a space being formed between the middle portions of the said upright and bar, a pivot pin having its end portions supported in the middle parts of the said upright and bar, a cutter lever engaging with the middle part of the pivot pin and working in the said space, a guide arm for the cutter lever secured at one end to the said bar adjacent to the lever pivot and projecting laterally from the said bar and parallel to the cutter lever and bearing against its rear side and preventing the cutter lever from being pressed rearwardly away from the stationary blade, and a blade secured to the front side of the cutter bar and having a sharp cutting edge which cuts off the soft metal against the sharp cutting edge of the stationary blade.

In testimony whereof I have affixed my signature.

OSCAR ALEXANDER GOETZE.
